The Difference - December 2013

Over 50 years of improving silage quality

There is a long tradition of using acid based silage additives in Northern Europe. Initially only formic acid was used. We have produced formic acid at site Perstorp since the fifties and have sold it for the purpose of ensiling since the 1960s. Realizing the great benefits of using acid based silage additives, we also started to blend propionic acid (another product that is manufactured at site Perstorp) into the silage additives to increase the performance of the products. The most recent innovation sees the salts of these organic acids used to buffer silage additives for safer handling and easier transport.

I know you are thinking this is impossible and wrong, right? You are correct, it is impossible. Weaning simply can’t be rushed. Let’s keep this thought in mind and think about the way we look at the weaning process in piglets. Most piglets are weaned between 3 and 4 weeks of age, which is very soon, but until now the most economical solution.
